> ---------------------------------------------------------------------------------
>
> Key: HDFS-9098
> URL: https://issues.apache.org/jira/browse/HDFS-9098
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: erasure-coding
> Affects Versions: 3.0.0
> Reporter: Zhe Zhang
> Assignee: Zhe Zhang
>
> Apparently the interleaving of events among {{StripedDataStreamer}}'s is very
> tricky to handle. [~walter.k.su] and [~jingzhao] have discussed several race
> conditions under HDFS-9040.
> Let's use FaultInjector to emulate different combinations of interleaved
> events.
> In particular, we should consider inject delays in the following places:
> # {{Streamer#endBlock}}
> # {{Streamer#locateFollowingBlock}}
> # {{Streamer#updateBlockForPipeline}}
> # {{Streamer#updatePipeline}}
> # {{OutputStream#writeChunk}}
> # {{OutputStream#close}}
